The construction for remedying the water seepage problem is quite difficult, and the durability and the reliability of the construction quality are difficult to ensure. Therefore, effective measures are needed to reduce the accumulation of leakage water and to drain it as quickly as possible.

At present, a subway channel structure adopts an off-wall ditch, and deformation joints adopt buried water stops. A buried rubber water stop is mainly used for water stop products arranged in concrete such as concrete deformation joints, expansion joints and the like, and has the capability of adapting to the expansion and contraction deformation of the concrete by using the elasticity and the structural form of rubber materials. The buried rubber water stop is correctly laid at the deformation joint position of the subway station, so that the water stop function can be better played. The side wall and the deformation joint leakage water flow into the station main body structure from the wall ditch and flow into the station water collecting well from the station hall layer water drainage hole. Although the deformation joint adopts the waterproof measure of the buried water stop belt, the phenomenon of serious water seepage still occurs in the deformation joint in practice, and the phenomena of water seepage, wet stain and the like often occur in the deformation joint.
